U.S.-Sweden Cooperative Research: Numerical Studies of Vortex Matter in High Tc Superconductors and Superconducting Films

9901379团队该奖项支持与瑞典Umea大学理论物理系的Peter Minnhagen和Peter Olsson合作的PI和研究生。该项目将集中于涡旋线和点涡旋模型的数值模拟，以研究与高温超导和超导薄膜行为有关的问题。将PI在三维波动涡旋线平衡行为方面的经验与瑞典小组在动力学模拟方面的经验相结合，将有可能探索与高T_c超导体涡旋线动力学有关的几个高度热门和相关的问题。其中包括约瑟夫森等离子体共振和涡线液体中的磁通流动阻力。合作的一个主要组成部分将是使用UMEA现有的专门超级计算机设施，这将极大地扩大国内研究活动的范围。

9901379TeitelThis award supports the PI and graduate students in a collaboration with Peter Minnhagen and Peter Olsson of the Department of Theoretical Physics at Umea University, Sweden. The project will focus on the numerical simulation of models of vortex lines and point vortices, in order to investigate problems relevant to the behavior of high- Tc superconductors and superconducting films. Combining the PI's experience in the equilibrium behavior of fluctuating vortex lines in three dimensions with the Swedish group's experience in dynamical simulations will make it possible to explore several highly topical and relevant problems related to the dynamics of vortex lines in high- Tc superconductors. These include the Josephson plasma resonance and the flux-flow resistance in the vortex line liquid. A major component of the collaboration will be the use of specialized supercomputer facilities available in Umea, which will greatly broaden the scope of the domestic research activities.
